Agricultural Mobile Apps: A review and update of calculator apps

This article provides a review and update of some of the current “calculator apps” for agriculture. These apps can assist in calculating such things as the optimum fertilizer N rate, grain yield estimates, tank mix requirements, crop nutrient removal rates, and other features.

While these apps can often help you make quick decisions in the field from planting to harvest operations, always make sure to check with your crop consultants, agents, and Extension specialists since this kind of specific information may vary depending on the soil types, yield potential, and environments.

Stay tuned for more in this series of annual reviews and updates on Ag-Apps from our KSUCROPS Crop Production team and the K-State Department of Agronomy! More updated lists of Ag-Apps will be included in the next several editions of the Agronomy eUpdates.

For this series of articles, we have grouped Ag-Apps into the following 10 classifications:

  • ID Apps: For identification purposes (weeds, insects, diseases, and nutrients)
  • CALC Apps: For calculating purposes (nutrient removal calculations, tank mixes, volume to spray, etc.)
  • SCOUT Apps: For scouting purposes or for geo-positioning (soil sampling, recording notes, soil types, etc.).
  • ECON Apps: For checking grain prices, market evolutions, fertilizer price trends, news and finances.
  • GUIDE Apps: For diagnosing crop production issues in the field, primarily related to field guides (crop management: insect, disease, weed, and more).
  • LIVESTOCK Apps: Apps related to the animal side, nutrition, health, and information on markets.
  • IRRIGATION Apps: Apps related to field crop irrigation and water application.
  • MACHINERY Apps: Apps for associated with agricultural equipment preparation, inventory, providing information of the machine.
  • GAG Apps: GAG (General Ag-Apps) for general use, weather-related, for meetings, for reading magazines, among several other Apps’ properties.
  • NON-AG Apps: For general use from e-readers to calculators, email, calendar, picture editing, and more.

2. Calculator Apps

These Apps are primarily utilized for calculation of planting, spraying, fertilizing, and harvesting purposes; and for estimating yields.
